In a recent newsletter, from Monday 24th November 2025, Mark featured an item about levels of CO2 in the atmosphere which was contributed by Mike Kearsley. Mr Kearsley sounds like he's been swayed by various sources of climate change disinformation. Mike asked us to specify what the optimum level of CO2 in the atmosphere should be.

The IPCC (Intergovernmental Panel on Climate Change) published the AR6 Synthesis Report: Climate Change 2023 in 2023, which summarises five years of reports on global temperature changes, fossil fuel use and likely climate impacts.

In his introduction to the Newsletter in late July Craig mentioned the materials science news around the possibility of room temperature superconductivity, with a compound called LK-99 being announced out of a research team in South Korea. At the time there was a lot of skepticism about this claim.

One of our regular readers (Hi Ray... and Paul) has requested we put a date on our newsletters, so you'll be receiving this on 31st July, 2023.

Keith Muir responds to Barry Brill's article, A Climate of Hope, in NZ Skeptic 108.

I agree with Vincent Gray (NZ Skeptic 107), it is not possible to determine an average temperature for the Earth. However it is important to note that even the alarmists agree that the Earth is not warming and has not done so for about 17 years. The British Met Office even predicts it is not going to do so in the near future.

Real science operates by collecting data, inventing theories, developing models and making predictions that can be tested. If predictions fail, theories must be modified or discarded.

When I sent my letter to the NZ Skeptic (Spring 2003), I did not expect vehement denials in the next issue. Such debate is, of course, healthy and occasionally useful. My letter, though, was not intended to cover the whole subject; merely to offer some points to ponder. The responses have been rather more thorough, and I feel I must defend my position.

New Zealand Skeptics walk happily on red-hot embers, protected by the laws of physics. Fijian firewalkers, however, are said to stroll across white-hot stones. How do they do it?
